The cobalt(II) chloride catalyzed Peterson rearrangement reactions between sulfinyldi-(pyrazolyl) and aryl(pyridyl)methanone derivatives yield di(pyrazolyl)(pyridyl)hetero-scorpionate ligands. Reaction of these ligands with Mn(CO)5Br in the presence of a silver salt produces the monometallic complexes [κ3-PhC(pz)2(2-py)]Mn(CO)3}(O3SCF3) (1a), [κ3-PhC(pz)2(2-py)]Mn(CO)3}(PF6) (1b), [κ3-PhC(4-Mep
